NixOS silently doesn't generate Device sections if videoDriver is not recognized

[lukateras]

This is an improvement request.

I've set services.xserver.videoDriver = "i915" and it resulted in no Device sections in xserver.conf generated by NixOS, and in services.xserver.deviceSection being ignored.

It might make sense to raise an error if services.xserver.videoDrivers is not empty and contains no recognized video drivers.

Couldn't we fix this with a types.enum ?

If this is still important to you, we ask that you leave a comment below. Your comment can be as simple as "still important to me". This lets people see that at least one person still cares about this. Someone will have to do this at most twice a year if there is no other activity.

Here are suggestions that might help resolve this more quickly:

1. Search for maintainers and people that previously touched the related code and @ mention them in a comment.
2. Ask on the NixOS Discourse.
3. Ask on the #nixos channel on irc.freenode.net.
